摘要： A first electromagnetic valve (100) closes an inflow port (121) and that a plunger (11) slides in a pump chamber (12), thereby compressing fuel flowing into the pump chamber (12) and discharging the fuel to the outside. The fuel supply control device includes a number-of-revolutions sensor (51) for sensing the number of revolutions (R) of a camshaft (8). In a case where a discharge instruction signal is not turned on and where the number of revolutions (R) sensed by the number-of-revolutions sensor (51) is not less than a specified number of revolutions (Rth), even in a case where the fuel does not need to be discharged to the outside, a controller (5) closes the first electromagnetic valve (100) in such a way that the plunger 11 compresses the fuel.

摘要： In a common rail type fuel injection system (1), fuel in a fuel tank (7) is sucked by a feed pump (11) and fed to a pressurizing pump (4) . Fuel pressurized in the pressurizing pump is supplied to a common rail (2). The pressurized fuel accumulated in the common rail is injected into a cylinder of an internal combustion engine from an injector (3) . All of these operations are electronically controlled by an electronic control unit (5) . To gradually suck air in the fuel tank together with fuel and to avoid air accumulation in a fuel filter, a relief valve (6) is connected to the common rail. The relief valve (6) is opened when the engine is idling thereby to increase an amount of fuel sucked by the feed pump (11) and to gradually suck the air together with the fuel. The relief valve is opened only in interval periods (INT) in which fuel is not injected from the injector.

摘要： In order to prevent a damage on a component forming a pressure feed fuel passage and to reduce a fuel injection pump in size and weight, the pressure feed fuel passage having fuel discharge passage (32), fuel chamber (33) and accommodation hole (34) formed in respective cylinder heads is formed straightly in respective cylinder heads (12, 13), and has communication port (32a) for communicating with fuel pressure chamber (30) and fuel outlet (34a) which has an opening at an outer peripheral wall of the cylinder heads (12, 13). Fuel pressurized in fuel pressure chamber (30) at the cylinder head (13) side is introduced into fuel chamber (33) of cylinder head (12) via fuel passage (42a) and fuel lines. Fuel pressurized in both fuel pressure chambers (30) is merged at fuel chamber (33) of cylinder head (12), and is supplied to a common-rail via fuel passage (41a).
